I am starting with fastmodel and getting Android booting on it .I am currently using RTSM_VE for A15 to start with and NFS filesystem. UART is simulated as ttyAMA0 and logs could be captured through it. The plan is to support A9, A15 and A15 + A7 combinations.

Hello,

Sorry if I am late to chime in, but Virtual Open Systems has already done some work regarding Android on A15 FastModels. You can find a proof of concept guide/tutorial on our homepage.

I have looked at your work and tried the images,its good work done by you guys.

As a base kernel we use the latest kvm-a15-v6 branch, together with the attached Android patch set and kernel configuration.

Most things seem to work, although performance is far from perfect, as any rendering to the framebuffer can slow things to a drag. Also, for the time being sound doesn't work and there is no USB for Fast Models (no USB storage and some applications depend on it). Booting seems to be working for both NFS and MMC (less that 2GB image) but MMC seems to be a bit faster in my experience (although NFS is more convenient). Logcat still complains about various stuff and I guess that a lot of things could be improved.

Currently I have android booting to console with dmart's kernel plus androidization topic branch. GUI is crashing since CLCD driver is not working with device tree. I have also seen that mmc (less than 2 GB image ) performance is much better than NFS. I could use adb over TCP.

For the Android userland you should use this set of patches against AOSP. If not, SystemUI will always nag you with an exception pop up and Wallpapers and Gallery won't work. Alternatively you can just run "pm disable com.android.systemui" and the nagging pop up will vanish but wallpaper rendering still won't work. I've already tried successfully the Linaro Android Images for Versatile Express and they are working, but the mentioned SystemUI exception still remains.

We have a different patch to get around the missing OpenGLES support. But the performance while using our patch and the set of patches you mentioned could be very different.

If you need further details please let me know.

Sincerely, Alexander Spyridakis.
